I chose the hand because 1. It the second most naked part of your body in public,first is the face. 2. Your fingers can make a fist 3. its easier and faster to wrap and unwrap the bandage 4. I saw something similar in a Sylvester Stallone movie where he shoots someone from a false cast on his arm .This is an inspired or copied idea. Items needed - Crepe Bandage / Medical Tape - Medical Adhesive tape - Item to hide - Cling Film / Food wrap to save your item from water or dust - Mild body powder ( optional)

Steps to do - Wrap your item in cling film - powder your hand if needed. - roll over the crepe bandage once or twice - place the item in a comfortable position and continue roll crepe over it - fasten it by its holders - feel your movement ( THE BANDAGE MUST'NT BE TOO TIGHT [ BAD FOR BLOOD CIRCULATION] OR TOO LOOSE[ ITEM MIGHT FALL OUT] ) - Wrap medical tape to make it seem more genuine

You can try the plaster cast or the quick drying casts too but I havent tried them myself.
